The blue Lancer, Ireland's child of light, the Hound of Culainn, and the Weilder of the Cursed Spear. Cu Chulainn. Cu is probably one of the most powerful servants in all of Fate. He can be summoned as 6 of the 7 classes but is probably strongest as a Lancer. He wields his Gae Bolg and uses it as his Noble Phantasms. The first being Gae Bolg: Cursed Spear Stikes With Death that has the unique effect of having a 100% chance to hit the target with a near complete chance of piercing their heart. His other Noble Phantasm is him throwing his spear at mach 2 and killing his opponent with the force. He's a pretty cool character too, being very noble and just a cool dude to hang with.
